WILLIAM H. HILL AND HERBERT B. WRIGHT, OF CHICAGO, ILLINOIS.

DUMP-WAGON Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed October 3- 1905- Serial No. 281.146.

To all whom it may concern:

Be it known that we, WILLIAM H. HILL and HERBERT B. WRIGHT, citizens of the United States, and residents of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dump-Wagons, of which the foldurable in construction and will not have any small parts or chains which will be apt to become broken, or to give trouble; and to provide means whereby the doors may not only be dropped to dumping position, but may be raised up alongside the sides of the box to get them out of the way of the dis charged material, and also means whereby either bottom door may be dropped without freeing the other one.

The invention consists in the novel features of construction and arrangement of parts which will be described and claimed hereinafter and which are shown in the accompanying drawings, showing an embodiment thereof, in which: I

Figure 1 is a side elevation of the dump wagon, Fig, 2 is a detail showing the bent door shaft or rod, Fig. 3 is an end view of the wagon, Fig. 4 is a View showing the locking catches for the doors, Fig. 5 is an enlarged detail of said catches, and Fig. 6 is a detail be turned in a short space.

showing the cranks for operating the catches.

According to our invention, the wagon body 7 is preferably carried on side beams 8 which extend along the top of said body and are then bent down to rest on the axle in the rear, and bent down and in to rest on the turn-table 9 at the front' The arrangement should be such that the front wheels may turn under the frame so that the wagon may The drivers seat 10 is so placed that the operating levers, to be described hereinafter, will be within convenient reach. We prefer to make the wagon of all steel construction, but of course wood or other suitable material may be used in its construction.

The wagon box is provided preferably with two bottom doors 11, these doors being provided with loops or fastenings 12 which engage with rods 13 on the sides of the box to form hinges and also guide means for swinging the doors out and up alongside of the box. These rods or guides are secured at the top and are bent in and up at the bottom, these upwardly bent portions being held in keepers or bearings 14 in which they are free to slide. The lower parts of the rods, or the part forming the hinge proper, may then be adjusted ,by means of the turn-buckles 15. This will provide means whereby the bottom doors may be adjusted so that they will be tight, notwithstanding any wear which may occur to the doors or to the hinges. This is an especially important feature for wagons used in hauling stone, sand or the like, such material causing rapid wear on the operating parts. The doors swing down and out as shown particularly in Fig. 8. The doors will drop to the lowest dotted position shown in said figure when the holding catches are released, and may then be closed again or swung up on the outside, as shown in the highest dotted position, by means of the door operating device. As these are duplicates, it will only be necessary to describe the one for one side, and for this reason, some of the parts have been omitted from the drawings for convenience in illustration.

A bent shaft 16,.shown in Fig. 2, extends the full length of the door and has its bearing 17, on the door, and end bearings 18 on the box. This shaft is provided at the front end with a lever 19 by means of which it may be turned in one direction to close the door, after it has been opened, or may be swung in the opposite direction to bring the door up to the side of the box, in order that the wagon will clear the load just dumped, whether it is This is a feature which we believe will add greatly to the convenience in operating the wagon, and one which has not heretofore been put into use. By means of this construction, we also do away with the chains which have been used for such pur ose and which give a great amount of troub e.

The door may be held in any position by the ratchet 33 and pawl 34. The door is held in closed position by means of catches or hooks 20, one at each end of the box for each door. These catches are secured to and operated by sprin s 21 which extend up and I over the top of t e box in order to give them driven ahead, or turned shortly to one side.

a good bearing asthey su port-the load. These springs press the catches normally in to engage the door, and the tension onsuch springs may be adjusted by the rod22-whioh passes through holes in the brackets 23, these holes being arranged at different heights and at different distances from the box. v

The catches are operated by means of crank rods 24, such rods having their bearings in boxes 25 and 26 on the ends of the wa on body; the. former being-made-inta gra 1y with the. bearings- 18,-. and .the latter. serving to hold thetwo adjacent ends of the. rodsatone end ofthe body. Theserodsare preferably madeseparateso that either door may be dropped.v as desired but onerod might be made to operate both catchesat one end if i were thrown out.

desired. The. frontend rod is operated by means of a-lever 27, and in order'to throw the catch on the raekendsimultaneously, this lever is connected by nansof a rodxZS-to a. crank. lever 2.9'onthe end ofthe back fed as shown in Fig. 1, the lever being shown. in this position in full lines as though thecatches The crank part ofthe rod 24 passes through an opening in the catch 20 as shown in Fig. 5, the arrangement being such that, as .thelever 27. is thrown rearward andheld by the springlock30, the.catch; is locked as shown in the full: lines. Then as the lever is. released from the lock and swun out ashort distance, the crank part wil come into the larger openingand willallow the catches to. swingfreelyeither out, orin to engagethe door. A.still further movement of the lever 27 will cause. thecrankito engage thecatch and throw-it out as shown indotted lines. In order. to reduce the wear andfrice tion when the, catch is being thrown out to release the bottom, weprovide the-bearing box 31with the roller 32 therein in the engagiIng edge ofthebottomdoor as shown in Having, thus described, our invention, what we claim and desire to secure by Letters Patent is.

1. The. combination of a wagon box, a. bottom door for. said box, hinge. members on said door, Vertically adjustablerods on said box adapted to engage with said hinge mem bers, and means for, adjusting said. rods,

2. The combination of awagon box, doors for. the bottom of saidbox,- loopson said doors, and adjustabl'erods along the sides of said. box with: which said loops engage, the

arrangement being, such that the doors can be raised up alongside said box.

3. The combination with a wagon box, of adjustable rods on the side of said box, and a. bottom door having bearings engaging with said rods.

4. In a device of the characterset forth the combination with a wagon box of a swinging door hinged to the said box with slidable hinges and a bent shaft arranged lengthwise of said door, said shaft having bearings on thewagon. box and also bearings on said door, the arrangement being, such. that the door maybe. operated by meansof saidshaft, said slidable hingeproviding for a lateralmovementxof the door.

5. Awagon box provided with a bottom door, a bent shaft arranged. longitudinally ofsaid box, bearings on said. box for engagement with; theends of said shaft, bearings on said door forengagement with theoffset portion of said shaft, and means for swinging said shaft for operating said door.

6. The combination" of a wagon body, bottom. doors for said body adapted to swing down, a, bent shaft engaging with bearings on said door and having bearingson said body, and a leverfor swinging said shaft ,to operatethedoor-eitherto close the same or to swing it-up along the side of the body.

7. In combination, a wagon body, a longitudinal door pivotally, attached to said body, cranks pivoted adjacent to the outer lower corners of the ends of said body, a, shaft connecting the outer ends of. said cranks and extending-longitudinally of said door and engagin therewith, and means for turning said cran s to close said door or to swing said door down and up alongside. the sides of-said body.

8. The combination of a door-catch, a,

bent rod having a crank portion en aging with said catch, the opening throug said catch for the rod being so shaped that when the rod is in one position the catch will be locked to hold the door, when the rod is swung to the next position the catch will be,

free to move, and, when the rod is swung-still further the catch will be thrown out of engaging position..
